The invention discloses a multifunctional nursing bed. The bed comprises a bedstead, a bendable bed surface positioned on the bedstead, a sitting drive mechanism and a turnover mechanism, wherein the bed surface comprises an upper body moving part, a lower body moving part and a fixed part; the sitting drive mechanism inclines the upper body moving part and the lower body moving part; the turnover mechanism comprises a left turnover frame and a right turnover frame; the bed surface comprises a left bed surface and a right bed surface, and the left bed surface and the right bed surface are in a comb shape integrally and oppositely interpenetrated; the left turnover frame and the right turnover frame respectively comprise a vertical beam II supporting the left bed surface or the right bed surface and end beams arranged at two ends of the vertical beam II, and a rotating shaft I of which the axis is parallel to the vertical beam II is arranged at the other end of each end beam; the turnover mechanism comprises rotating shaft lift mechanisms which are arranged on the bedhead and the bed tail; each rotating shaft lift mechanism comprises four centro-symmetrically arranged guide rail slide mechanisms and corresponding slide lift mechanisms; an axle hole matched with the corresponding rotating shaft I is formed on a slide. The multifunctional nursing bed can change body positions or a pressed part of a patient in the turnover process.
